Erbauer Ground HSS Drill Bit 4mm Pack of 5
Bought 2 packs of these just in case they blunted quick as i needed to drill about 20 holes in thin sheet steel pretty quick. I'd previously bought Dewalt bits for a similar job - i might as well have put matchsticks in the drill for all the use they were. So i was a bit over cautious because of this.. I ended up using only one of these fabulous bits - well impressed.

strong drill bit
Strong drill bit tried drilling cast iron with other hss drill bits which blunt very easy and using these it cut many holes and the price is amazing.

cut through metal
first time of buying this Erbauer product of drill bits, am impressed ,cuts through clean metal with no problem once I got rid of rust with angle grinder. You can hear and see the bit cutting through the metal.I would recommend these drill bits, give them a try better than some expensive ones. Reason for only 4 stars for reliability, first time of trying.
